4.0 INSTALLATION

The Model 1060 is easy to install. After configuring the DIP switches and DCE/DTE switches, connect the two twisted pairs using one of two methods: terminal blocks or RJ-11 jack. Figure 2 (below) shows the location of the terminal blocks and RJ-11 jack, as well as the female DB-25, on the rear of the Model 1060.

4.1 TWISTED PAIR WIRING OVERVIEW

These short range modems are designed to work in pairs. You will need one at each end of a 4-wire twisted pair circuit. The pairs must be "dry" (unconditioned) metallic wire, 19 - 26 AWG. The smaller gauges limit distance somewhat compared with larger gauges. When you have completed wiring for your data circuit, the pin connections should be as shown below:

XMT +		RCV+	} One Pair
XMT -		RCV -
G	To Shield (Optional)	G
RCV -		XMT -
RCV +		XMT + } One Pair

4.1.1 TWISTED PAIR CONNECTION USING TERMINAL BLOCKS

If your two twisted pair line terminates in bare wires, strip the ends and connect the individual leads to each Model 1060's terminal block. Be sure the end-to-end connections follow the diagram above.

4.1.2 TWISTED PAIR CONNECTION USING RJ-11

If your two-pair cable is terminated in an RJ-11 plug, you may use the RJ-11 jack in the back of the Model 1060 to make the connection. The RJ-11 jack on a Model 1060 series Short Range Modem is prewired for a standard TELCO wiring environment. To be sure you have the right wiring, use the diagram below as a guide.
